Themostatic bimetal types
The type of thermostatic bimetal depends on the application and the available space. Elements can be roughly classified into four main groups:
Beams develop nearly linear motion. Coils (spiral, helical and double-helix coils) Disks move linearly or discontinuously (snap-action).
Formed elements include a wide range of regular or irregular shapes. The U-shape is very widespread. This type of element is employed when the available space will not permit the use of long, flat beams.
Generally speaking, coils are used wherever extensive motion is required, while beams are required for smaller movements to trip operating mechanisms.
some basic mechanism of bimetal strip :
1.Simple temperature -controlled switch
This type of mechanism is usd for drect switching of an electrical circuit or a mechanical part. When current is passed directly through the element , slow contact motion may result in sparking between the contacts.
Faster response and higher sensitivity reduces the risk of sparking between contacts in elements with direct electrical heating .
3.Auxiliary thermal switches
The thermostatic bimetal does not form part of the electrical circuit and responds solely to the ambient temperature .
a permanent magnet resistrains deflection until the thermostatic bimetal had developed a force sufficient to overcome that of the magnet ,thus causing the contacts to spring parts . Conversely , the contacts close when the element has cooled down.
Thermostatic bimetal functions:
The effects of thermostatic bimetal curvature in response to a change in temperature are utilized in practical applications to achieve different aims. These can essentially be described by the following functions :measuring, limiting,controlling,compensation,pulse-generation,retardation.All these functions overlap to a certain extent so that a particular application may fall under several categories .
Temperatures and certain electrical variables and their rate of change can be regulated by calibrated systems.
Spiral thermometers, Ammeters
Trip functions are required at certain upper or lower limits in order to initiate or to cut out an operation.
Automatic circuit breakers
Motor protection switches
Within a certain range,functions are cut in or out ,or circuits made or broken,in order to maintain a certain average setting.
Electric iron controls, Bypass valves
A deviation from the initial condition is compensated for by the thermostatic bimetal action.
Color television tube compensation,Measuring instruments with compensation for fluctuations in ambient temperature.
An operation is triggered at clocked intervals.
Flasher relays, Hotplate heating coils
An incoming signal (e.g. current)will only trigger an operation after a defined delay period.

-Sea Shipping: Usually it will take around 20-30 days to arrive most countries. You need to make custom clearance when goods arrive your side. It is the cheapest way of shipping. So if you are not in a hurry and have big quantity of goods, you can choose sea shipping.
-Air Shipment:Usually it will take around 3-10 days to arrive most countries. You also need to make custom clearance when goods arrive your side. It is more expensive than sea shipping, but cheaper than by express.
International Express: Such as DHL, FedEx, UPS, TNT, TOLL, DPEX, USPS and so on. You can choose Economy Service which is cheaper than normal service if the goods are not urgent. It is one kind of Door to Door service. Normally if the goods volume is not very big, you don’t need to make custom clearance in your side. The courier will send the goods to your door.
